Marni. WINDOW-BASH.

atented Sept. 26, 1911.

Application fi led October 7, 1807. Serial No. 898,201.

Be it known that I,"Enwann A. Sammie, a citizen of the United States of America,

cisco and State of California, have invented new and useful Improvements in Metal Win dow Sash,of which the following is a specification. This invention relates to improvements made in rails and stiles for the construction sheet-metal strip are united by an interlocking joint of novel construction, and having a groove to receive the sash so formed as to confine the glass on both sides of the pane. This feature of the invention is applicable,

- also, to the construction of the bottom-rail and the.top-rai1 ofthe sash.

Theinvention consists further in a tubular sheet-metal sash of novel construction having atop-rail with a slot extending ver- I tically and longitudinally through it, for inserting the glass-pane from above, and a removable closing-strip having the two-foldj function of confining the glass in place and of closing the slot in the rail. I ,The invention consists further in a novel manner -of uniting the stilesand rails -together at the corners without the use of corner-posts, or blocks. In this feature of theinvention,"the parts or members areso arranged'that they serve tohold and retain the glass-pane in place without other fastening means than the usual putty or cement;

and the parts com osing the joint are in turn held in together hy theflglass and are prevented from springing apart or becoming separated after the glass is set.

' The nature of these improvements and the manner in which I proceed to produce, ap-' .ply and carry out the same in the construction of a sheet-metal window-sash, are explained at length in the followin de'fscrip-- tion in which referenceis had to t e accompanying drawings forming part of this specification.

- Figure 1 of the drawings represents front-elevation a metal-window sash in which the stiles and rails are formedor constructed and joined together according to my in-, vention. Fig. 2 is a longitudinal sect onal view, on the line w-w, Fig. 1. Fig. 3 is a transverse section, on, an enlarged scale, of

the bottom-rail of the top-sash and the topof the an rail of the bottom-sash in their relative position when the sashes are closed; showing a closing-strip of noveLform' placed between the adjacent rails for closing the opening between them. Fig. 4 is a transverse section through the bottom-rail, and Fi 5 a similar section through the top-rail, oth on an enlarged scale. Fig.5. is a front-elevation,

also on an enlarged scale, of a ortion of the left stile and the top-rail joine to it. Fig. 7

is a longitudinal section through the lower portion of the left stile, and the bottom-rail oined to it. Fig. 8 is .a top-view of Fig. 6.

ig. 9 is a transverse section taken diametrical y through the top-rail on the line 1 Fig. 6. Fig. 9 is an end. view'of the closing-' stri in the top-rail. Fig. 9 is a detailof the ridge-piece for the screw-bolt by which the parts of the top-rail are drawn together fastened. Fig. 10 is across-section taken diametrically through, the stile or the bot-' tom-rail, showing theglass setin the 'oove. Fig. .llillustrates one way in wh ch the 'oint is made, and the cove for the ormed in the stile and t e bottom-rail. 12 is a top-view-in detail of the parts composing the top-rail before they are joined to the stile. Fig.1 a side-view of the bottom-rail before i is united to the stile. Fig.

14 illustrates ai'iother'wa in which the edges 3 of the sheet-metal are oined together and the oove for the glass is formed.-

T e tubular rail or stile of my invention is produced by bending a stripof sheetmetal a, into a cylindrical shape around a former K (see Fig. 11) and in or .by thev same operation uniting the edges of the-strip by overlapping and bending them at right angles in such manner as .to interlockthe two edges and also form a groove or channel of rectangularshape in cross-section from end to end of the "tube. This operation is best carried out or performed by bending the strip a around the former Xin which is the other angularly bent edge so that it be vary in thickness. Another advantage attained by this construction of joint is that the interlocking members are pressed tightly together, and are also so covered by the glass that the putty or cement which is ordinarily used to fix theglass in the sash may in most cases be dispensed with when a thoroughly Water-tight joint is desired. The small quantity of cement that will be required for that purpose can readily be applied between the glass and one side of the groove to fill the crevice, Another advantage in this joint is that it will take glass panes of different dimensions in thickness, and will accommodate itself to slight variations in the thickness of the glass, without aflecting the strength or the tight character of the joint; as the greater the pressure of the glass against the sides or the bottom of the groove, the closer will the members 2*& or 2-5 be pressed together.

Suflicientmetal being provided for. the lap, the two thicknesses that lie over the channel are pressed down into it by any proper means, such as a plunger or bar of the required rectangular shape. in cross-section, and of proper length to fill the channel from end to end, with the result to bend the portion 3" at right angles and form the three members 3 i5, and at the same time bend the overlapping portion 2* twice at right angles, and thereby form the two membered 'hook or angularly bent edges of the strip .2-2 The hooks thus form the sides and the bottom of the channel or groove 6*.

The stile Av and the top-rail B and bottomrail B are joined together according to the manner of forming and uniting the ends illustrated in Figs. 6, 7, 8, 9, 10, 12 and 13.

The end of the rail-is cut on a bevel on the top and bottom sides at equal angles leaving the tangs or narrow strips 68 on the ends,

1 and the lip 7 on the'bottom. Slits 9 are cut in the stile on diametrically opposite sides to admit the tangs 6-8, and the last named parts being inserted from the outside are clenched on the inside, as seen in Figs. 7 and '8after which the joint is finished by soldering orrbrazingthe parts along the seams 10 where the beveled edges meet the sides of the stile.

The lip 7 on the bottom of the rail should fit-the groove in the stile, so as to close the groove at the end, and a tight joint is produced place.

This-construction gives a strong and a "stiff joint without the use of separate cornerposts or angle-pieces.

, As the parts 'are put together in a permanent-inanner and'thesash'is finished before at that point by soldering the lip in application, tembe'ri; 1908.

the glass is set,'the' form of the groove obviously requires some provision for inserting the glass from above through the toprail, so that it can be entered and pressed down into place in the grooves of the stiles and the bottom-rail. For that purpose the top-rail is formed according to the manner illustrated in Figs. 99=*,9", in which the top-rail is composed of two separate curved halves or segments joined together by bridge-pieces 16 on the inside of one segment, and screws 15 which are inserted from the outside through the opposite segment and the bridge-piece opposite; that part being threaded to take the ends of the screws or bolts. The edges of each segment are turned inwardly, and the segments are held by the screws at proper distance apart to admit the glass between them.

- When the glass is inserted and pressed down in the sash, the closing-strip D filling the opening above the glass is secured in place between the members of the rail by the screws 15, which fasten the two members together. The closing-strip D is best formed by bending a strip of sheet-meta1 in the shape of a rectangular tube, with the parallel sides 13 placed at proper distance apart to fit closely against the 1nwardly turned ends along the top sides of the railmeinbers, and being of such length also that the bottom 14; of the closing-strip will rest on the top of the glass.

- This construction has the effect to unite the members of the top-rail rigidly and hold the glass in place. I

The modification illustrated in Fig. 14 in which the groove to admit the glass pane is formedin the rail at .a point diametrically opposite the joint 20 which united the edges of the tube, is adapted more particularly for a heavy rail or stile of relatively large diameter, Where the curvature of the tube willpermit the forming of a. flat joint on the external face of the tube. The construction illustrated in Figs: '10 and 11 is better adapted for a rail or a stile of relatively small diameter, for the reason that it enables the joint to be situated wholly within the groove, thereby leaving the external surface of the tube smooth or unbroken particularly along the portion which fits and travels in the window-frame.

I do not in this case claim a window sash having astile or rail formed of a strip of sheet metal having inturned portions extending'longitudially of the strip, and the opposite edge portions thereof overlapping,

and being disposed at righh angles to one of the inturned portions, whereby there isformed a groove or recess for the glass such as illustrated in Figs. l,- 8 and 10 of this case, as such subject-matter is claimed in my Patent No. 897,414 dated Sepapart and to close the opening along the top after the glass is inserted, a bridge piece mounted Within one segment and means en:

gaging with the said. bridge-piece and with the other segment for drawing the segments together against the sides of the glass. A,

2. In a metal window-sash, ato -rail-c'omprising two separate segments aving inwardly turned edges, a removable strip between said segments adapted to maintain the segments at roper distance apart to permit the insertlon of the glass-pane between them, said strip also closing the space between the rail members along the top, a

bridge-piece arranged behind the inturned edges of one segment and means engaging with the said bridge-piece and with the other segment for drawing the segments together and securing the said closing-strip in place.
